Lesson

Are you ready?

Multiplication looks at equally sized groups. Can you solve this problem?

$3\times9$3×9

Learn

Let's look at how to multiply numbers by $6$6.

$6$6 groups is twice (two times) as many as $3$3 groups. Doubling means multiplying equally sized groups by $2$2.

Apply

$6\times3$6×3

Remember!

You can use a doubling strategy to multiply a number by $6$6. Start by multiplying the number by $3$3, then double the answer.

Outcomes

3.OA.C.7

Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g. Knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of grade 3, know from memory all products of two one-digit numbers.
